FLIER SPINNING AND TWISIING MACHINE.

Specification of Ietters Patent.

rammed July 2v, 1915.-.

Original application iiled July 14, 1913, Serial No. 778,840. Divided vand this application led October 23,

To all whom it may concern.'

Be it known that I, HERMANN CARL HEINRICH LnRCr-I, a citizen of the German Empire, residing at Amerika-on-the-Mulde, in the Kingdom of Saxony, Germany, have invented certain new and useful Improvements in Flier Spinning and Twisting Machines, of which the following is a specilication.

My invention relates to rimprovements in rIhe present invention has for its objectv to provide an improved flier spindle bearing of the most simple construction, and which will work in an absolutely and permanently reliable manner at all speeds.

rIhe invention consists substantially in providing a double bearing casing of known construction in which the inner sleeve that receives the spindle and that is made spherical in the usual manner in the plane of engagement of the driving cord, is caused to bear in a movable manner with its hollow spherical base likewise upon a sphere arranged in the outer bearing casing.

The invention is illustrated by way of example in the accompanying drawing, in which a is the fixed bearing sleeve adapted to be screwed into the spindle rail, o the spindle composed in the usual manner of a steel body carrying` on its unsupported cylindrical upper part in addition to the driving whirl c the nier and the bobbin.

The middle portion of the spindle Z) is provided with a rounded collar e working in an enlarged part 7 of the bore of the in* ner sleeve d. The ball c' forms the footstep bearing for the spindle b. The inner sleeve l is bulged at its bottom which serves as a bearing for the ball c'. The hollow spherical foot of theainner sleeve 0l bears upon a ball g which in its turn bears upon a convex surface 7c of the bottom cap Z. 0f the Outer sleeve a. VIn my improved bearing the spindle is therefore no longer mounted directly in the fixed bearing sleeve a, but is mounted indirectly in a sleeve al which in its turn, owing to its bearing upon a ball, allows the spindle to rock freely even when the outer sleeve a should not be in an exactly vertical position or be screwed askew in to the spindle rail.

ll/hile in describing the invention reference has been made to a particular embodi ment thereof, I wish it to be understood that my invention isnot limited to the example shown in the drawing, and that various changes may be made in the construction. llhe invention may'also be applied to ring spindles.

I claim as my invention:

l. A bearing for flier spindles, compris ing an outer casing an inner sleeve in said casing for receiving` the spindle, said inner sleeve having a. spherical bearing at its upper end in the plane of engagement of the driving cord, for engagement with the outer casing,and also having a hollow spherical base, a ball arranged in the outer casing upon which said base bears in a freely movable manner, for the purpose of effecting an automatic centering. tendency at all speeds.
